Remove jwage/purl dependency

This is an alternative to #16.

Since the package was only used to replace the host, wp_parse_url() should work just as fine.

If the PHP requirement would be increased to PHP 5.4+, parse_url() could be used directly.

@swalkinshaw Wanna review? 🙂

We already have "php": ">=5.4.0". Is the = the issue here?

[swissspidy]

Kinda. The thing is that parse_url() behavior was changed in PHP 5.4.7. So if you're running PHP 5.4-5.4.6, then wp_parse_url() is the safer bet.

But even if you're running a newer version of PHP it doesn't really hurt to use wp_parse_url().

This is a WP plugin after all so wp_parse_url is fine 👍
